Hey Guys,
I am going to look at a 2003 Monster 620 tomorrow. Are there any trouble spots on these bikes that I should focus on?
Welcome.
Make sure the gauges show no signs of moisture inside.
Maintenance records are a plus.
No major trouble spots. Things to watch are fuel tank rust (if its metal) and fuel tank expansion (if its plastic).
Make sure it's got 3 keys. Two black and one red. If a black key is missing, not a big deal. IF the red key is missing you might walk away. W/o the red key it's nearly $2000 in parts to get the bike going again if the immobilizer system is activated.
